Segfault when linking with -pthread on recent stable/10 ARM

[Arjan van der Velde]

This seems to be related to qemu. To my understanding qemu does not fully support threads. I have been running into exactly the same problem on stable/10 and also tried both with and without native-xtools, to no avail. Linking to pthreads does work on stable/10 running on an actual ARM, without problems.

Last week I updated jails to recent stable/10 and started to see the same issue on 2 ports (net/openldap24-client and net/ntp). I noted there were a lot of ARM MFCs recently so probably we got a regression at some point.
